| Abstract: | A tractor electro-hydraulic suspension semi-physical simulation system was designed with the tractor LOVOL TG1254 as the research platform. The hardware platform of the system mainly included a tractor hydraulic circuit, a sensor and a data acquisition device. The software platform used SIT module, combined with LabVIEW and MATLAB to establish a controller model. An adaptive control algorithm was designed to realize the force control, position control and force-position comprehensive control of the system. A field experiment showed that the transition time of the system was less than or equal to 6s, and its overshoot was less than or equal to 25%. The control process was stable, the ploughing depth was stable and the operation quality was promoted. |
